Subject: [FlyRotary] Re: Short intake manifolds

 

Paul,

There was a discussion here a few weeks ago regarding 'back pulses' in the

intake manifold.  Sorry, that may not be the correct term.   IIRC, seems a

short manifold  may have issues, one being fuel droplets being expelled the

opposite direction.   Let me suggest the potential for it to pool in your

'outer chamber' and another potential for a backfire to ignite it.    Hopefully

that is blatantly wrong so those who know will step in and straighten it out. 

 

I have a short intake manifold with a TWM TB and no issues with backfires, fuel droplets, or whatever.  Works just fine.
